WELLS BARKER, OF NASHVILLE, MICHIGAN, ASSIGNOR TO THE BARKER AUTOMATICSCALE COMPANY, OF SAME PLACE.

REGISTER.

SPECIFICATION forming part of Letters Patent No. 431,178, dated July l,1890.

Application filed January 23, 1890.

To all whom, it may concern:

Be it known that I, WELLS T. BARKER, a citizen of the United States,residing at Nashville, county of Barry, State of Michigan, have inventeda new and useful Registering Device, of which the following is aspeciication. y

This invention relates to that class of registering devices in which aseries of rotating rings are employed one within the other andbearingnumericalcharacters upon their outer faces; and itl has for itsobject the below described and claimed peculiar construction andassociation of parts.

In the drawings forming a part of this specification, Figure 1 is afront elevation showing the front wall of the case removed and portionsof the rings being broken away and certain lettered details incross-section. Fig. 2 is asection on line 2 2 in Fig. l, looking from apoint at the right hand. Fig. 3 is a section on line 3 3 in Fig. l. Fig.4 is a section on line 4 4 in Fig. l, looking from a point at the left;and Fig. 5 is a back view of a broken portion of one of the ringsenlarged.

Referring to the lettered parts of the drawings, A is the case in whichthe rings B C D are arranged one within the other. There is a slotthrough the front wall of the case, as indicated at 'it by dotted linesin Fig. l. The characters representing the numbers are prestnted at saidslot, and said characters are placed upon the front face of the ringsand entirely around the same, a portion of said characters being shownon the rings at the right in Fig. l. Vith the rings in their normalposition as here shown nothing is presented at the slot n except a rowof ciphers. The figures on each ring are from 0 to 95)- that is, thefigures, which are of course arranged to read from left to right, beginwith an 0 at the opening n on the inner ring and end one space below theslot with 99. The other` rings are numbered inv like manner, with theaddition of an 0 at the left of l 2 3 4 5 6 7 8 9 on each additionalring.

The operation will be explained below. The rings are provided with teetharound their inner edge, as at 3 in Fig. 5, and on the back at theirouter edge, as at 7 in Figs. 4 and 5, except the outer ring B, has noteeth Serial No. 337,858. (No model.)

on the back, but is provided with teeth around its outer edge, as inFig. l. The rings are hung upon pins fi, as in Figs. l and 2,said pinsbeing attached to the case A at the top. Guides c c, having a notch 6,Fig. 3, which catches over the inner edge of the rings, thus keeping therings from getting out of their proper place, and thus preventing themfrom binding one against the other, are arranged at the sides andproject from the back wall of the case A and outward between the rings.The ring B is provided on the back with a latch a, Figs. 3 and 4, whichis passed through a hole in said ring to engage one of the notches 7 ofthe ring C against the resistance of the spring oc. Said pin is thrownout by coming in contact with inclined lugs c, which lug is attached tothe case A. This action takes place when the ringB has made onerevolution, and as it continues to move the ring C is jogged onenotch,and when this action has taken place the latch a will have passedthe lug c and the spring @o will have disengaged the latch ct from theteeth 7 of the ring C, as in Fig. 4. At this time the outer ring will bein the position it now occupies in Fig. l, and the ring C, which willhave been jogged one notch, will register l at the opening n, and saidl, together with the two ciphers at the right on ring B, will registerlOO. In short, the outer ring B makes one revolution while the ring C ismaking one notch, or, in fact, makes one hundred revolutions to onerevolution of the ring C. The rings lC and D have a like construe` tionof latch a and in a like relation to each other, as do the rings B andC, as shown in Fig. 4. Thus the ring C makes one revolution while thering D is making one notch, or makes one hundred revolutions to onerevolution of the ring D, and the characters are thus presented at theopening n to register any number from one up to one less than a million.g

A less number of rings or a greater number bearing like characters andin like relay tion with each other may be employed.

While any suitable mechanism may be employed to rotate the rings onenotch at a time,I have shown in Figs. l and 2 a simple constructionwhich will illustrate the idea.

IOO

At E is a power-shaft upon the case A, and having near one end a tootheddisk F. At 71. is a vertically-playing rod, which is provided with ahook at the lower end for engaging with the teeth of the outer ring B.This hooked rod raises under the resistance of the springf. The rod 7Lis provided at the top with a yoke G, rigidly attached thereto, saidyoke being provided with vertically-clon gated slots, through which thepower-shaft E passes, and by this means thc rod 7i is guided and kept inproper position.

In the upper end of the yoke G is a roller S, adapted to engage theperiphery of the toothed disk F. Thus each tooth acts as aneccentric-cani on the roller S and causes, in connection with the springf, the rod 7L to play up and down alternatclythe distance of one toothon the outer edge of the ring B.

It will be observed that the teeth at the inner edge of each ring 3, U,and D t over the respective pins 'L' /L' L', as seen in Fig. l, and saidteeth lift over the pins the distance of one tooth at a time when cachring is moved one notch at a time. The rings are thus locked at thepoint at which they indicate and will so remain until the operativepower moves them, as before described.

This device will be found useful for various purposes, among themregistering weight in connection with scales and registering quantitiesof grain and the like.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, its- The combination of.the case, the series ot rings one within the other and bearingnumerical characters, said rings having the inner teeth and the teeth onthe back side of all except the outer ring, said outer ring having teetharound its outer edge, pins attached t0 said case upon which said ringsare hung, the guides attached to said case and catching over the inneredge of the rings at the sides, the spring-actuated latches, theinclined lugs with which they come in contact at each revolution ot` therings, and suitable means for jogging the rings, substantially as setforth.

In testimony of the foregoing I have hereunto subscribed my name inpresence of two witnesses.
